I have created a web service with VB .NET 2005 that is connecting to a DB2 database through a third party ODBC driver of DataDirect and simply adds a row to the table.The service is working properly.Because I had to move the service to a server and the DataDirect driver that I have works only for client use, I needed to change the ODBC and use the DB2 Connect ODBC driver for the cause.

I'm using VB 2008, I haven't used it much, only a little bit for my execl and word macros but now I have to make a little lightweight program for myself.What I can't find is the method of detecting when scrollUP is used. The idea here is that I need to register when scroll up is used, and then perform a keyboard command. So basically I would like to Copy with scrollUp for example, but this need to work outside the progam/form.

I would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:
' Resize Image Before Uploading to DataBase
Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?

I've recently created a MVC 3 ASP.net application (using VB). I have also created forms validation by running aspnet_regsql. I used this to create the table in the same database as my application uses. I am trying to work out how to create a new model, with a FK from the Users table. Do I have to reverse engineer the validation tables to create models in my application? right now, the tables only exist on the SQL 2008 database, as they were created by running the aspnet_regsql command, and do not exists as models in my ASP.net solution. Here is the code I have now, for a model I would like to add a FK to (as a one-to-many relationship):

how I can Encrypt the data that is requested/sent? I wrote an application that connects to MySQL to INSERT/UPDATE/READ information from/to. The application also connects to a website of mine.

View 2 RepliesI have a text file that has thousands upon thousands of URL's in it. I wrote a program to go to each of these links in succession (via For loops, obviously) and to grab a piece of information from them.Now to the problem. When I get to about 2300 or so, I get the error "COMException was unhandled by user code. The requested resource is in use. (Exception from HRESULT: 0x800700AA)" at the line "WebBrowser1.navigate(linkstocheck(i))"
I set linkstocheck = all lines of the text file. I get the same error even when I get the link directly from the lines of the text file. Does anyone know how I might go around this? Maybe catch the exception, wait half a second, then continue where it got the error?

View 1 RepliesI am using a MasterPage with a dynamic menu bar across the page. If the user has requested a redirect back to the login (home) page, I don't want to log them out but I do want to hide the menu bar. Currently I am using whether the user is authenticated to control if the menu bar is visible or not.Basically, I want to always hide the menu bar when on the login page.The menu is rendered prior to the page itself so I need to be able to read the redirect request to see if the login page is the destination.

View 2 RepliesI have a datagridview on a form which is populated with data from our backend database. A few of my users are experiencing a problem when they select all the cells in the datagridview and try to copy and paste the contents into something such as Excel.
The error is: Requested Clipboard operation did not succeed.
Having searched for information on this error it appears that if a process has the clipboard already open (such as office) this will cause the exception being thrown (which is a system.runtime.interopservices.externalexception), usually when the code calls the clipboard.settext method (which I do not). However my form and its code does not even contain anything to do with clipboard manipulation, copy and paste or anything remotely to do with using the clipboard so I am unsure as how I can actually catch this exception and just report back to the user?

So I am using a user to run the following code that is a member of the "User" group on a Windows 7, x64 machine. I am trying to use impersonation (by logging in as a user that is part of the Administrator group) to allow the current user to read from the registry.
